JR-C / JR20-C


All information contained in this manual, unless indicated, is valid for both JR-C and JR20-C models.

JR-C and JR20-C models from KOSMOS serie are digital indicators fully configurables that allow input type

selection in order to be used as needed. Available signal inputs are the following:

LOAD CELL (30mV, 300mV)

The basic instrument consists of a soldered assembly composed of a main board, a display and an input signal circuits. It can also be incorporated, as an option, an extra plug-in 2 SPDT 8A relays circuit output which is isolated

from signal input and power supply. This extra circuit has independent connectors that are located on the rear part

of the instrument once it is installed.

Specially designed for direct connection to Load cells, both models have 4 digits, configurable decimal point and 2 LED’s for setpoints status indication, they are easy to scale into desired engineering units, directly by frontal keys

or rear input signal value in teach mode. They also provide a 24V DC output for sensor excitation.

JR-C model is provided with 14mm-high digits and maximum display range of -9999 to 9999 whereas JR20-C

has 20mm-high digits and a maximum range of -1999 to 9999. JR20-C has a larger display to provide a better reading at longer distance, although minus LED sign is integrated in the most significative digit instead of being

external, as in JR-C model.

Both devices have three frontal keys to interact with internal software and set configuration in order to adapt their

function to particular applications. Device programming runs through some independent menus that show short messages to easily identify input type and/or display configuration steps.

If relays output option card is installed, once it is recognised by the instrument, activates its own configuration

menu which is only visible under this conditions.

Device description

Dimensions and mounting

To install the instrument, prepare a

92x45mm panel cut-out and slide the unit inwards making sure of placing the sealing

gasket between the front side panel and the frontal bezel.

While holding the unit in place, put the fixing clips on both sides of the case and

slide them through the guide tracks until they reach the panel at the rear side.

Press slightly to fasten the clips to the latching slots

on the case and get the unit fully assembled and close fitted to achieve a good sealing.

To remove the instrument from the panel, pull outwards the rear fixing

clips latching tabs until they are disengaged, then slide fixing clips back over the case.

INPUT CONFIGURATION

When connecting instrument to Power supply, display test begins automatically to check the good function of LED’s

and digits, once this test is finished, display shows internal software version and then the unit goes to RUN mode.

Configuration software has a hierarchical structure composed of a number of menus and submenus. By pressing ENTER key, display shows “Pro”, a new pressing brings access to main menu where appear configuration menus,

that is, input configuration (InP), display configuration (dSP) and setpoints configuration (SEtP). This last menu

only appears if 2RE output option card is installed.

If configuration is totally locked-out, when pressing ENTER key to get into main menu, display shows “dAtA” instead of “Pro”. This indicates that it is only possible to see programmed information and that it is not allowed to

modifiy any parameter from the entire configuration. In this visualization mode, the instrument automatically switches back to RUN mode after 15 seconds since last key press.

Configuration menu

The instrument provides 3 keys for progressing through the

menus and submenus and for data introducing/modifying:

ENTER: Vertical displacement / Validates data.

UP: Increases active digit value.

SHIFT: Horizontal displacement / Changes active digit.

Input configuration

Once inside each menu, all configuration parameters are sequentially shown and they can then be introduced or

edited by pressing ENTER key. Numeric values must be entered digit by digit, first selecting digit and then changing its value. When the display reach desired value, a new ENTER key pressing validates data and routine

goes forward to next configuration step.

Data entered or changes made during configuration are stored in device memory only when programmation

routine belonging to the respective submenu is completed, not before. On last routine step and after having pressed ENTER key, display indicates “StorE” and the unit goes back again to RUN mode.

DISPLAY CONFIGURATION

Display Programming

Display scaling

IMPORTANT IN “tEAC” MODE:

To ensure the best accuracy, both points 1 and 2

should represent extreme process limits.

TRHOUGH FRONTAL KEYS CONFIGURATION “SCAL”

Input and display values are configured manually through the three keys of the instrument. This method is suitable when signal values supplied by the transducer at each

extreme point of the process are known.

REAL INPUT SIGNAL CONFIGURATION “tEAC”

Input values are directly introduced from CN2 input connector just at the moment of signal capturing at

each point of the process. Display values are configured manually through the three keys, as in the previous case.

This method is suitable when signal values at each point are unknown but, it is possible to lead process to the conditions

defined by these extreme points.

WEIGHTED AVERAGE FILTER “FiLt”

Sets low-pass filter cutoff frequency (Fc) which allows the instrument to smooth out undesirable display reading fluctuations.

Display scaling is necessary when adapting display reading to a particular engineering unit. Display range can be

configured between -9999 and 9999 for JR-C (14mm-high digits) or between -1999 and 9999 for JR20-C (20mm-high digits).

Display scaling is a linear process that consists in introducing two input values, referred as Input 1 and Input 2,

and their respective display values, referred as Display 1 and Display 2. On the basis of this proportional

relationship internal software calculates display value that would correspond to a given input value. Decimal point position would complete required engineering units indication.

It is possible to scale display in an increasing or decreasing proportional mode depending on whether if second

display value (DISP.2) is greater or less than the first (DISP.1). In an increasing mode, display value increases proportionally to the input value whereas in a decreasing mode, display value decreases. The left figure below

shows both scaling modes.

The right figure shows an example for a 150kg and 2mV/V load cell with a 10V DC

excitation. Decimal point is situated between third and fourth digit of the display.

method, input signal value must be present at the conector at each

point that is intended to be configured.

SETPOINTS CONFIGURATION

If 2RE output option card is uninstalled, the instrument keeps setpoints last configuration in memory, though it can

not be visualized.

Thanks to this feature there will be no need to reconfigure relays setting when 2RE output option is again installed if the same configuration is required.

The third menu “SEtP” only appears when two relays output card is

installed. For further details on function modes please refer to the corresponding OUTPUT OPTION part later on this manual.

Programming steps are equal for both relays on each “SEt1” and

“SEt2” submenus. The parameters to be configured are the following:

In addition to already known functions used to browse through the configuration menus and submenus, introduce

and/or modify existing values and parameters, the instrument provides some more added functions.

If 2RE output option is installed, it is possible to access to setpoints value

configuration without having to enter main menu.

To access this submenu, from RUN mode and after ENTER key is pressed, simply press UP key while “Pro” is displayed.

TARE function activates by pressing UP key (or by closing contact between pin 4 and pin 5 from CN2 input

connector, see page 9). Current display value is then stored (or added) in memory and the instrument shows (by default) "0.00" or "0.0", depending on whether configured input range is 30mV or 300mV respectively. At the

same time, after the first digit (from the right), a point starts flashing indicating that the instrument has stored a TARE value.

It is possible to tare instrument as many times as needed, as long as the accumulated value does not exceed the limit value defined by the working range. Otherwise overflow indication "OuE" will be displayed. Stored tare value

remains in memory although power supply is removed.

This device detects and stores in memory maximum and minimum values reached by the input signal. This values remain in memory although power supply is removed, as well. When pressing repeatedly SHIFT key, MAX/MIN

function shows saved maximum and minimum values in display since last RESET function activation.

In order to differentiate this values indication from a mode RUN indication, decimal point blinks during the time

these values are showed. The unit automatically switches back to RUN mode after 15 seconds have elapsed since the last key press.

First SHIFT key pressing shows “MAH” in display followed by the maximum value, a second pressing now shows “Min” followed by the minimum value and finally, a third pressing shows “run” to back again in an instant to RUN

mode.

MAX/MIN RESET function activates when visualizing maximum or minimum values SHIFT key is pressed for at least 5 seconds. If maximum is the displayed value, current input signal value will replace the previous maximum

saved value. In the same way, current input signal will replace saved minimum value while is the minimum the

displayed value.

TARE RESET function activates by pressing UP key or maintaining remote contact closed for at least 3 seconds. This is only possible in RUN mode. After that time, stored value will be added to the current display and erased

from memory and the flashing point will disappear.

SHIFT key configuration for MAX/MIN function (MAH)

In each case lock-out is activated by selecting “yES” option and deactivated by selecting “no”.

Setpoints 1 and 2 configuration lock-out is available only when 2RE output is installed.

If 2RE output option card is uninstalled, the instrument keeps setpoints

last configuration in memory, though it can not be visualized. There will

be no need to reconfigure setpoints lock-out when 2RE output option is again installed if the same configuration is required.

If “LiSt” option is selected, display will show momentarily

“tLoc”. Total configuration lock-out is activated by selecting “yES”, then routine directly jumps to TARE

function and SHIFT key for MAX/MIN function lock-out configuration before the unit goes back to RUN mode.

When total lock-out is set, no data can be entered

or modified, although it will still be possible to visualize all programmed parameters. Under these conditions when

entering main menu, initial indication will be “dAtA” instead of “Pro”.

On the other hand, when “no” option is selected, routine

move on to next step to configure a partial lock-out.

When a partial lock-out is set, only non-locked data can be entered or modified. Under these conditions

when entering main menu, initial indication will be “Pro”.

JR-C / JR20-C


Once the instrument programming is completed, if there are parameters that are going to be frequently changed, a

partial lock-out is recommended. A total lock-out is recommended when configuration parameters will be constant for a long time.

Changing default security code and keep new one in a safe place is also strongly recommended.

SHIFT key lock-out for MAX/MIN function is configurable in the same

way as previous configurations.

When lock-out is enabled (selecting “yES”) it is not possible to visualize maximum or minimum values by pressing SHIFT key, although

instrument internally continues detecting and saving new extreme

values reached by input signal.

output deactivation edge, obtaining as a result the ‘hys-1’ delay as indicated on the right figure.

Note that outputs activation is not affected by

hysteresis and they activate in each case just when setpoint ‘SET’ is reached by display.

Hysteresis delay for OUT1 (HI mode) and for OUT2 (LO mode)

2RE output option allows JR-P and JR20-P models to perform control operations and limit values treatment via ON/

OFF logic outputs. It is supplied as an independent card that is connected to main board without any additional operation since internal software recognizes it once it is installed. There is no need to read the manual since all

information required is contained in this user manual.

Alarms are independent, they become activate when display value reach setpoint level programmed by the user.

For a correct configuration it will be necessary to define function mode, as well.

Both output actions can be deferred by a

configurable time delay from 0 up to 99.9 seconds.

Time delay activation starts when display value reach each setpoint ‘SET’ either increasingly or

decreasingly, obtaining the ‘dly’ delay in output

activation/deactivation as right figure shows.

To physically install the output option, the electronics assembly should be first lifted out from the case. Use a

screwdriver or similar to slightly press both side tabs until the rear case is released. Then broke the junctions from the corresponding polycarbonate cover in order to obtain the required orifice in the case. This orifice will allow 2RE

connectors come out through instrument rear part once it is installed.

Install 2RE option on the indicated location pushing slightly down until both connectors get perfectly together. For

best installation, it is recommended to solder this card to the main circuit making use of the copper pads on both sides of its insertion pin and those surrounding the circuit hole where it is inserted in.

Once 2RE is installed, carefully put the circuitry again inside the case verifying that circuits slide properly without

much effort through rear case internal guides.

Each output card is supplied with an adhesive label that indicates wiring connections. To help identifying terminals,

this label should be placed in the upper side of the unit case. Besides its own connections, there are other output options indications for other outputs that can be installed in other model indicators.

Main circuit

Once 2RE is installed and instrument is again inside the case, 2RE connectors should come out

through the obtained orifice as this figure shows.

Fix here connections label

When rear case is completely released, junctions must be broken to remove this polycarbonate cover

to allow 2RE option connectors come out.

To lift out electronics assembly from the

case, slightly press both side tabs until

rear case is released.

WARNING:

Disconnect all power and rest of input signals connected to the indicator before installing or

extracting the output option card.
